It spread through English and later British colonisation and developed into an imperial crown, which rooted it in the legal lexicon of all 15 Commonwealth realms, their various dependencies, and states in free association with them.
[6] Warren J. Newman described the Crown is "a useful and convenient means of conveying, in a word, the compendious formal, executive and administrative powers and apparatus attendant upon the modern constitutional and monarchical state.
"[7] Lord Simon of Glaisdale stated:[8] The crown as an object is a piece of jewelled headgear under guard at the Tower of London.
The term "the Crown" is therefore used in constitutional law to denote the collection of such of those powers as remain extant (the royal prerogative), together with such other powers as have been expressly conferred by statute on "the Crown".Lord Diplock suggested the Crown means "the government [and] all of the ministers and parliamentary secretaries under whose direction the administrative work of the government is carried out by the civil servants employed in the various government departments.
[10] In William Blackstone's 1765 Commentaries on the Laws of England, he explained that "the meaning therefore of the legislature, when it uses these terms of empire and imperial, and applies them to the realm and crown of England, is only to assert that our king is equally sovereign and independent within these his dominions, as any emperor is in his empire; and owes no kind of subjection to any other potentate on earth.
[14] The term the Crown then developed into a means by which to differentiate the monarch's official functions from his personal choices and actions.

"[49] Canadian academic Philippe Lagassé found the crown "acts in various capacities, as such: crown-in-council (executive); crown-in-parliament (legislative); crown-in-court (judicial).
Today, it is considered separate in every country, province, state, or territory, regardless of its degree of independence, that has the shared monarch as part of the respective country's government; though, limitations on the power of the monarch in right of each territory vary according to relevant laws, thus making the difference between full sovereignty, semi-sovereignty, dependency, etc.
[72] In criminal proceedings, the state is the prosecuting party; the case is usually designated (in case citation) as R v [defendant],[73] where R can stand for either rex (if the current monarch is male) or regina (if the monarch is female), and the v stands for versus.
Until the end of the 20th century, such case titles used the pattern R v Secretary of State for Exiting the European Union, ex parte Miller.
In Scotland, criminal prosecutions are undertaken by the lord advocate (or the relevant procurator fiscal) in the name of the Crown.
The Crown can also be a plaintiff or defendant in civil actions to which the government of the Commonwealth realm in question is a party.
